This Rear Section Of Front Frame, Spring Mount from Auto Rust is designed to repair the front frame section where the leaf spring perch is mounted. This is behind the front axle. The frame in this area seems to trap a lot of dirt, road debris, and mud, as well as water is able to get inside the boxed frame. Once its trapped it starts to rust from the inside out, and can fail before you even know you have a problem. Our repair kit is manufactured from precision CNC cut sections of heavy gauge steel, and includes a new leaf spring mounting perch. This Safe-T-CapTM saves time and money with this smart fix for rotted frames.
